'Acronym' in Simon Spurrier's novel The Culled

Since my discussion with 'Anonymous' over the meaning of 'acronym', I keep finding examples of writers using 'acronym' when others would prefer 'initialism'.

The latest example comes from Simon Spurrier's post-apocalyptic novel The Culled. I quote:

We reached the front of the queue and caused something of a commotion. For a start, Nate's branding could hardly be covered with a simple piece of rag – unless he was prepared to submit to blindfolding, which he wasn't – but it was the nature of the mark itself that really got them riled. They kept exchanging looks, clenching their jaws, wondering out loud if they should fetch the 'Em-Bee'.

More f***ing acronyms.

Obviously, this novel is written in the first person so it could be that the narrator's understanding of 'acronym' differs from the author's. MB (or 'Em-Bee') here stands for 'master of bids'. Oh, and the stars are mine – I try to keep the blog reasonably safe for work.
